Which of the following is a controlling factor in very fast heterogeneous reaction ?
Correct answer: A. Heat and mass transfer effects
- A. Heat and mass transfer effects
- B. Pressure
- C. Temperature
- D. Composition of reactant
Explanation
When a heterogeneous reaction is very fast, the intrinsic surface reaction is no longer rate-controlling. Heat and mass transfer through the surrounding phases or boundary layers then control the observed rate.
